white lies

Noun

white lie (plural white lies)

1. (idiomatic) A deliberately untrue statement which is intended to produce a favorable result; especially, one which is judged to be better than an overhonest alternative, as for example to remain polite in a superficial social exchange, or to pick one's battles.
   • The prevarication and white lies which a mind that keeps itself ambitiously pure is as uneasy under as a great artist under the false touches that no eye detects but his own, are worn as lightly as mere trimmings when once the actions have become a lie.1861, George Eliot [pseudonym; Mary Ann Evans], chapter XIII, in Silas Marner: The Weaver of Raveloe, Edinburgh; London: William Blackwood and Sons, →OCLC, part I, page 239
